The spelling of the French phrase "Ouster le Mer" can be explained through IPA phonetic transcription. "Ouster" can be transcribed as [uːst̪əɹ], with the long "u" sound and a dentalized "t" sound. "Le" is simply pronounced as [lə], and "Mer" as [mɛə], with a diphthong in the second syllable. When pronounced together, the phrase sounds like [uːst̪əɹ lə mɛə], with emphasis on the first syllable of "Ouster" and a slight pause between "Ouster" and "le Mer".
